Completed restoration, Westchester County
Craftsmen who still believe in the original steel
Steel casement windows built before the 1950s were engineered to outlast the buildings around them — if someone knows how to keep them running. That's the trade we've practiced since 2010: freeing painted-shut sashes, restoring worn hardware, and welding rusted frame corners back to true, without erasing what makes a historic window worth saving.
Every job, from a single cottage casement to a full commercial storefront, gets the same shop-level attention — hand-fabricated hardware when an exact match is no longer sold, glazing compound applied the traditional way, and a lead-safe process on any job that touches old paint.
- Lead-safe certified for on-site & shop-based repair
- Custom hardware fabricated when originals are discontinued
- Residential, commercial & historic-property experience

"Pesantez Steel Window Repair does amazing work! Joe restored (to pristine condition) 23 windows and 1 double door, the total of which involved over 375 separate panes of glass, on a 95 year old home. They also went beyond what was agreed upon in the contract and replaced several of the window sills at no additional charge. Joe and his two assistants (Freddy and Teddy) were extremely neat, polite, organized and professional and they took every precaution to keep the house clean and insulated. Further, through the entire job, which lasted about 7 weeks, they were on time and worked a full day. I would rate their professionalism and work product a 10 out of 10, and I very highly recommend them."
"First time using this company and I was very happy with Joseph and his team. The team was professional and neat. Our home is one year shy of 100, so you can imagine our beautiful leaded glass windows which are the original. Joseph replaced two full panels and you can't tell the difference from the original ones. The work was done in a timely fashion and on time. I would definitely recommend this company, their attention to detail is second to none."
"Pesantez Steel Window Repair did an amazing job restoring our 100+ year-old steel casement windows. Our windows were transformed from cracked, broken, and crumbling to positively gorgeous! Pesantez Window Repair does expert and impeccable work. Joseph Pesantez is knowledgeable, experienced, and an absolute pleasure to work with!"
"Very positive experience. Reliable and punctual. Repaired the cranks on two of our windows and did a great job! I was worried because the windows are very old and fragile and one of them no longer opened at all. Thanks to JP's careful work, the windows and cranks now all work perfectly and the price was reasonable too."
